another timing question to all that helped me with the last knock retard issue thanks, i took out some sensitivity and now its working great.
the car is still not opening up like it should and it breaks up and pops back at mid to high rpm
the not opening up i atribute to being pretty rich and the timing still being a little low ( new to tuning, baby steps) but i cant figure out the popping and breaking up. check out this log and the random dip in ignition timing under boost, no retard was recorded but the timing histogram def has some negitive numbers while i was in boost. according to my table timing should have been in the 13 degree range. before i saw this i gapped new plugs to .025, replaced the wires ( thanks MIGHTYMOUSE) and turned up the dwell time a little (10%), i also zeroed burst knock out of curiosity
any ideas what could be causing the crazy retard and unsteady timing
btw i see that the actual value for advance says like 36 degrees, for some reason that acts funny sometimes when i scroll through logs, that little flat spot before the dip is 14.5 degrees

good call guys, that fixed it, i thought i had disabled that but evidently i didn't
runs good now, feels a little sluggish still but i think that because i have the timing way low still, tomorrow i'm going to start creeping up the boost from 4 pounds to 7.
thanks again i would have chased that forever before i found it
